Readmission after spinal epidural abscess management in urban populations: a bi-institutional study.
This study examined 90-day readmission rates and causes after spinal epidural abscess (SEA) occurrence in urban populations. Neurosurgery records from two large urban institutions were reviewed to identify patients who were treated with SEA. Out of 103 patients with identified SEA, 97 were included. The mean age was 57.1 years and 57.7% were male. The 90-readmission rate for all causes was 37.1% with infection being the most common cause. Patients with prior immunocompromised status or hepatic disease had higher odds of 90-day readmission after SEA treatment.

Social risk factors for medication nonadherence: findings from the CARDIA study.
The purpose of this study was to investigate the combined effect of social risk factors on medication nonadherence. Using data from the Coronary Artery Risk Development in Young Adults study, the results showed that low income and chronic stress are associated with medication nonadherence, and that the odds of nonadherence increase with the accumulation of social risk factors. These findings may assist with developing risk prediction tools to identify individuals who can benefit from adherence-promoting interventions.

Measuring cardiopulmonary complications of carfilzomib treatment and associated risk factors using the SEER-Medicare database.
This study’s goal was to measure rates of cardiopulmonary complications from carfilzomib treatment in patients with recurrent myeloma. Myeloma case data was extracted from the SEER-Medicare linked database from 2000 to 2013, and corresponding claims through 2014. There were 635 patients identified as being treated with carfilzomib. Of these, median age was 72 years, 55% were male, and 79% were white. Median duration of treatment was 58 days. Overall, 66% of patients had codes identifying cardiac or pulmonary adverse events. Cardiac adverse events included hypertension, peripheral edema and heart failure. Pulmonary adverse events included dyspnea, cough, and pneumonia.

Development and validation of a predictive model of the risk of pediatric septic shock using data known at the time of hospital arrival.
The purpose of this observational cohort study was to derive and validate a model of risk of septic shock among children with suspected sepsis, using data known in the electronic health record at hospital arrival. The investigators concluded that their model estimated the risk of septic shock in children at hospital arrival earlier than existing models. They indicate it leveraged the predictive value of routine electronic health record data through a modern predictive algorithm and suggest it has the potential to enhance clinical risk stratification in the critical moments before deterioration.

Elucidating the role of overweight and obesity in racial and ethnic disparities in cesarean delivery risk.
This study’s goal was to quantify the extent to which overweight and obesity explain cesarean delivery rates among women of different racial and ethnic backgrounds. Administrative records were used from New York City for 216,481 singleton, nulliparous births from 2008 to 2013. Risk ratios, risk differences, and population attributable fractions for associations between body mass index and cesarean, stratified by race and ethnicity was calculated. Black and Hispanic women had the highest cesarean rates attributable to obesity and overweight (17.4% and 14.6%) respectively.

Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Hospital experience predicts outcomes after high-risk geriatric surgery.
This study examined if there an association between a hospital’s annual volume of high-risk geriatric surgery and their risk of inpatient mortality, postoperative length of stay, and discharge to nursing facility. Using the 2014 National Inpatient Sample, older adults were identified who had undergone high-risk geriatric surgery. There were an estimated 514,950 hospital encounters at 3,115 hospitals undergoing surgery. A higher proportion of high-risk geriatric surgery patients was associated with decreased mortality and shorter postoperative length of stay. Higher volume hospitals were not associated with mortality but was associated with longer length of stay and decreased discharge to nursing facilities.

Paradox of glycemic management: multimorbidity, glycemic control, and high-risk medication use among adults with diabetes.
Researchers examined contemporary patterns of glycemic control and use of medications known to cause hypoglycemia among adults with diabetes across age and multimorbidity. They found that the proportion of patients achieving low HbA1c levels was highest among older and multimorbid patients. Older patients and patients with higher comorbidity burden were more likely to be treated with insulin to achieve these HbA1c levels despite the potential for hypoglycemia and uncertain long-term benefit.

Risk factors for severe opioid-related adverse events in a national cohort of medical hospitalizations.
The objective of this study was to identify independent risk factors for severe opioid-related adverse drug events (ORADEs) in hospitalized patients. This retrospective cohort study used data from medical patients hospitalized at US non-federal and acute care facilities with at least one pharmacy charge. They excluded patients with metastatic, hospice, or palliative care billing codes. Out of 731,208 hospitalizations there was a severe ORADE in 2727 (0.4%) of patients. Independent risk factors included advanced age, female gender, comorbidities, organ failures on admission, medication co-administrations, and characteristics of the opioids themselves. These risk factors can be used to inform physician decision-making and conversations with patients about risk.

Expectant management of hypertensive disorders of pregnancy and future cardiovascular morbidity.
The purpose of this study was to test the hypothesis that a longer length of time between diagnosis of hypertensive disorders of pregnancy and delivery is associated with increased risk of cardiovascular morbidity in the years after delivery. The investigators concluded that prolonged expectant management of preterm hypertensive disorders of pregnancy was associated with an increased risk of maternal cardiac disease in the ensuing years.

Long-term functional decline after high-risk elective colorectal surgery in older adults.
This study examined the long-term risks of functional decline after elective colorectal surgery in older adults. This retrospective matched cohort study used data from the Health and Retirement Study, a nationally representative, longitudinal survey of adults >50 years of age. This survey collected data on functional status, cognition, and demographics, among other topics. The survey was linked with Medicare claims and National Death Index data from 1992 to 2012 and used patients 65 years and older. Surgery patients did experience a greater likelihood of functional decline with or without complications compared to control subjects. The older the patient, the more likelihood of a functional decline occurring after surgery.

Machine learning prediction of mortality and hospitalization in heart failure with preserved ejection fraction.
This study developed models to predict the risk of death and hospitalization in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Data was used from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) clinical trial. Five methods: logistic regression with a forward selection of variables; logistic regression with a lasso regularization for variable selection; random forest (RF); gradient descent boosting; and support vector machine, were used to train models for assessing risks of mortality and HF hospitalization through 3 years of follow-up and were validated using 5-fold cross-validation. RF was found to be the best performing model for predicting mortality and HF hospitalization. Blood urea nitrogen levels, body mass index, and Kansas City Cardiomyopathy Questionnaire (KCCQ) subscale scores were strongly associated with mortality, while hemoglobin level, blood urea nitrogen, time since previous HF hospitalization, and KCCQ scores were the most significant predictors of HF hospitalization.

Novel risk factors for central-line associated bloodstream infections in critically ill children.
Central-line-associated bloodstream infections (CLABSI) cause morbidity and mortality in critically ill children. In this study the investigators examined novel and/or modifiable risk factors for CLABSI to identify new potential targets for infection prevention strategies. They found that novel risk factors for CLABSI in PICU patients included acute behavioral health needs and >80 CVC accessed in the 3 days before CLABSI. They suggest that interventions focused on these factors may reduce CLABSIs in this high-risk population.

Pre-operative, intra-operative, and post-operative factors associated with post-discharge venous thromboembolism following colorectal cancer resection.
Venous thromboembolism (VTE) is the most common preventable cause of 30-day post-operative mortality, with many events occurring after hospital discharge. High-level evidence supports post-discharge VTE chemoprophylaxis following abdominal/pelvic cancer resection; however, some studies support a more tailored approach. The objectives of this study were to (1) identify risk factors associated with post-discharge VTE in a large cohort of patients undergoing colorectal cancer resection and (2) develop a post-discharge VTE risk calculator.
